Description
Signal ix

Input

vector

<active>

Specifies the signal (a known convolution result)

Response response

Input

vector

<active>

Specifies the response

Sampling Interval interval

Input

double

1.0

Specifies the sampling interval. The default is <auto>, which corresponds to an automatically computed interval.

Normalize Response norm

Input

int

1

Specifies whether the response should be normalized

Wrap Response wrap

Input

int

0

Specifies whether the response should be wrapped

Deconvolution Type circular

Input

int

linear

Specifies whether the deconvolution is circular or linear. This will decide how the data points outside the input range will be treated.

Option list

  • linear :Linear
    Linear deconvolution will be computed. Data points outside the input range will be viewed as zeros.
  • circular:Circular
    Circular deconvolution will be computed. Data points outside the input range will be viewed as repetition of the data points within the range.
Output oy

Examples

1. To perform linear deconvolution with the signal in Column 1 and the response in Column 2 of the active worksheet, use the script command:

deconv ix:=col(1) response:=col(2)

2. To perform deconvolution to data using a pre-saved smoothing theme file, save your preferences in the deconv dialog, and then execute it by typing the following script command, using your own saved-theme title:

deconv -t "my deconvolution theme.oth"
